Question

While determining the density of the cylinder, a student noted the following readings
1. mass of the sphere= 81g
2. i) reading of water level in the cylinder without sphere in it = 54 ml
ii) reading of water level in the cylinder with sphere in it = 63 ml

On the basis of these observations, find the density of material of the sphere.​

Answer 1

so first lets take the mass

the mass of sphere=81g

volume= 63(volume with sphere) - 54( volume without sphere)=9ml

density=mass/volume

density=81/9= 9 g/ml or 9g/ml^3
